Traefik tutorial

Traefik erkennt automatisch Dienste aus Docker und Kubernetes.

Warum Traefik¶

• Auto-Discovery (Docker, K8s, Consul)
• Automatisches SSL (Let’s Encrypt)
• Dashboard
• Middleware (Auth, Rate Limit)

Docker-Setup¶

services: traefik: image: traefik:v3.0 command: - –providers.docker=true - –entrypoints.web.address=:80 - –certificatesresolvers.le.acme.httpchallenge.entrypoint=web ports: [‘80:80’, ‘443:443’] volumes: [‘/var/run/docker.sock:/var/run/docker.sock:ro’] webapp: image: myapp labels: - traefik.http.routers.webapp.rule=Host(app.example.com) - traefik.http.routers.webapp.tls.certresolver=le

Middleware¶

labels: - traefik.http.middlewares.rl.ratelimit.average=100 - traefik.http.routers.webapp.middlewares=rl

Traefik für Docker/K8s¶

Auto-Discovery + Auto-SSL = ideal für Cloud-Native.
